For Earth Hour 2012, vow to play your ukulele by candlelight. From 8:30 – 9:30 switch off your lights and be part of the movement.

The world will be a better place if we can recognize they symbolic importance of Earth hour which you can learn more about from WWF’s official video. In the meantime, the Twitterfeed for earth hour is posting minute by minute pictures of cities being part of earth hour.

If you play your ukulele by candlelight for earth hour, be sure to share a picture. You miss posting it to instagram (#earthhour) or the Flickr group , or any other of the methods proposed.

If you don’t know what to sing when you light your candles and pick up your uke tonight, you could always download this pdf of lyrics, charge your video camera ahead of time, and sing Edward Huang’s WWF Earth Hour Anthem. I don’t see any YouTube vids where someone’s done it on acoustic ukulele yet. And that would increase the song’s value — no electricity.
